Picnic Safety in Hot Weather: What Food Businesses Need to Know

With temperatures soaring across the UK, many people are making the most of the sunshine by heading outdoors for picnics, park lunches and beach days. For food businesses, this often means an increase in demand for sandwiches, salads, deli items, grazing boxes and takeaway meals.

While warm weather is great for sales, it also brings increased food safety risks. Higher temperatures create the perfect conditions for harmful bacteria to multiply, making it more important than ever for food businesses to ensure food leaves their premises in the safest possible condition.

Why Summer Increases Food Safety Risks

Food poisoning bacteria grow much faster in the “danger zone” between 8°C and 63°C. During hot weather, chilled foods can quickly rise above safe temperatures if they are not stored or transported correctly.

The UK sees millions of cases of foodborne illness every year, with warmer weather contributing to an increase in cases as bacteria multiply more rapidly in higher temperatures. The Food Standards Agency (FSA) continues to remind both businesses and consumers that maintaining the cold chain is essential during the summer months.

Your Responsibility Doesn’t End at the Counter

Although businesses cannot control how customers store food once they leave the premises, they can help reduce the risk by providing safe products and clear guidance.

Consider the following best practices:

Keep Food Properly Chilled

Ensure chilled foods remain at 8°C or below until the point of sale. Display refrigeration should be monitored regularly and temperature records maintained.

For businesses preparing picnic hampers or takeaway meals, consider packing chilled foods with ice packs or recommending insulated cool bags where appropriate.

Think About Shelf Life

Hot weather may not be the best time to prepare food several days in advance.

Review your production schedules and shelf-life decisions, particularly for:

• Sandwiches
• Prepared salads
• Cooked meats
• Dairy-based desserts
• Filled rolls and wraps
• Grazing boxes

Shorter display times during extreme heat may be appropriate to help maintain food quality and safety.

Prevent Cross-Contamination

Summer favourites often include ready-to-eat foods that won’t receive any further cooking.

Good separation between raw and ready-to-eat foods remains one of the most important controls in preventing foodborne illness.

Ensure staff continue to follow effective cleaning procedures, use separate equipment where required and maintain excellent hand hygiene throughout food preparation.

Help Your Customers Stay Safe

Many businesses now include small information cards with takeaway picnic boxes or catering orders. A few simple reminders can make a real difference.

For example:

• Keep chilled food cool until ready to eat. (e.g. with icepacks or in insulated bags)
• Use antibacterial gel or wipes before handling food or eating.
• Store food in a cool bag with ice packs if travelling.
• Avoid leaving perishable food in direct sunlight or warm vehicles.
• Eat chilled foods as soon as possible.
• Discard food that has been left unrefrigerated for extended periods in hot weather.

These simple messages demonstrate your commitment to food safety while helping customers protect themselves and their families.

Don’t Forget Allergens

Picnics are often shared between family and friends, making allergen management even more important.

Ensure all takeaway foods are correctly labelled or accompanied by clear allergen information. If producing picnic hampers or grazing boxes, check that allergen information remains with the food throughout transport and service.

Review Your Summer Food Safety Procedures

Hot weather is an ideal reminder to revisit your food safety management system.

Ask yourself:

• Are refrigerator temperatures being checked often enough? Can you do anything to keep temperatures as cold as possible?
• Is food preparation minimised outside chilled environments?
• Are delivery vehicles maintaining appropriate temperatures?
• Do staff understand the additional risks posed by hot weather?
• Are customers receiving appropriate storage advice?

Small adjustments during periods of extreme heat can significantly reduce food safety risks.

A Safe Summer Starts with Good Food Safety

Summer should be about making memories—not dealing with food poisoning.

By maintaining high food hygiene standards, protecting the cold chain and giving customers practical advice, food businesses can play an important role in ensuring outdoor dining remains both enjoyable and safe.

As temperatures continue to rise, now is the perfect time to review your procedures, refresh staff training and make sure your business is ready for the busy picnic season.

After all, good food safety is always in season.
